Application lecl February 16, 1917. Serial No. 149,099.

To all A11i/omit may concern.'

Be it known that l, FRANK M. MENDONCA, a citizen of the United States, residing at Hilo, Territory of Hawaii, have invented new and useful Improvements in Lamp- Burners, of which the following is a speciy fication.

This invention relates to lamp burners for kerosene lamps, and it has for its object to provide a lamp burner with a simple and improved extinguishing device whereby the flame may be extinguished without resorting to blowing down the chimney, an expedient which has frequently resulted in igniting the oil contained in the reservoir of the lamp, thereby causing disastrous accidents.

A. further object of the invention is to provide a lamp burner having a swingingly supported extinguishing' member and means whereby the same may be conveniently actuatcd.

A further object of the invention is to provide a device of the class described of simple and improved construction, wherein a stop member is provided to limit the movement of the swingingly supported extinguishing member.

lith these and other ends in view which will readily appear as the nature of the 1nvention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,

Figure l is a front view of a burner constructed in accordance with the invention, the cap of the burner having been partly broken away.

Fig. 2 is a horizontal sectional view taken through the cap and looking down upon the extinguishing device.

Fig. 3 is a vertical sectional view taken on the line 8 3 in Fig. 2.

Fig. 4': is a vertical sectional view taken substantially at right angles to Fig. 3.

Corresponding parts in the several figures of the drawing are denoted by like characters of reference.

The lamp burner A which is of ordinary conventional construction embodies a neck having a threaded portion l16, the perforated diaphragm 17 having upwardly extending chimney holders 1S, the cap 19 which is hingedly connected with the diaphragm, and the wick raising stem 19 having a button or handle 2O whereby it may be rotated.

The side walls of the wick tube C are provided with externally disposed pivots 21 affording supports for the extinguishing member B which is composed of approximately semi-circular side walls 22, 23 which are spaced apart and connected together at one end by an end wall 24, said end wall and side walls being preferably formed of a single piece of sheet metal which, after being out to the proper form, may be readily bent to produce the device. The side walls 22, 23 are each provided with an aperture 25 engaging one of the pivot members 21, and the side wall 22 is provided with a pinion 26 secured on the external face thereof in concentric relation with the aperture 25. Secured on the diaphragm 17 adjacent to one end of the wick tube C is a stop member 27 which lies in the path of the end wall 24 of the extinguishing member. The latter is so arranged and proportioned that in one position thereof the straight edges of the approximately semi-circular side walls will coincide with the top edge of the wick tube, being disposed approximately in the horizontal plane of said top edge while in another position of the extinguishing member the curved edges of the side walls 22, 23 will extend materially above the top of the wick tube. It is in this last named position that the end wall 241C engages the stop member 27. For the purpose of operating the extinguishing member there is provided a stem or shaft 28, suitably supported for rotation approximately at right angles to the wick raising stem 19, and having a button or handle 29 whereby it may be rotated. The stem 2S carries a segment rack 30 which meshes with the pinion 26. It follows that by rotation about its axis of the stem 28 the pinion 26 will be rotated, thereby swinging the extinguishing member about the axis of the pivot members 21.

The operation of this device will be readily understood. Vhen the straight edges of the side Walls or the extinguishing member are juxtaposed to the top of the Wick tube, the lamp may be Conveniently lightedrnnd will burn unobstructedly. To extinguish the flame it is only necessary to rotate the stem "28, thereby swinging the extinguishing member about the axis of the pivot members 2l, thereby Carrying the curved edges ofthe side walls 22, 23 above the iame which will thus be quickly smothered `-Without the least .danger of fire being projected downwardly. through .the Wick tube and ig-y niting the lgases contained in the lamp reser- Voir.

Having thus described the invention, What is claimed new is:

l. A lamp burner having a Wicky tube providedV With Lpivot members on the side Walls thereof, an extinguishing member swingingly vsupported-on the pivot members, said extinguishing member comprising approximately semi-circular side Walls and an end Wall whereby said side Walls are conneeted and spaced apart, means for actuat- .ing the extinguishing member, and a stop element supported on the diaphragm of the lamp burner in the path of the end Wall of the extinguishing member.

2. Alamp; burner having a Wick tube the side Walls of which are provided with pivot members, an extinguishing member swing inglyv'supportedion the pivot*y members, said extinguishing member; comprising side Walls and an end wall whereby said side Walls are connectedand spaced apart, a pinion iixed externally: on one of the side Walls inconeentrie relation to the axis of theI pivot members, al stem supported for rotation and havingan'aetuating handle, and a segment racl carried byfsaid stemand engaging the pinion.,
